Airmax Pond Dye Packets Nature's Blue Colorant for Large Pond & Lake, Beneficial UV Blocking Color Concentrate, Maintain Clean & Clear Pond, Fish, Bird & Animal Safe, Easy Treatment, 2 Soluble Packets

Have a 3 acre pond, and use this to help keep pond clear of unwanted growth. We are and have been very happy with this product

Works well, color is very nice. We have approx. 100,000 gallons and if I could go back, I would only use one pack for a slight tint. So, before you throw two packs in, try one a wait a day or too. Wear gloves, this stuff takes days to get off your hands. No problems with the fish.

Lasts 3 months without minimal rainfall.

What i liked: Almost no mess and powerful enough to give a 1.5acre pond a pleasant blue tint.Why i gave it a 4 instead of 5: While the packets keep most of the powder contained, the plastic bag containing the packets had a small amount of fine powder that wasn't inside the packet. After i threw the packets in the pond i discovered my hands were.....blue. Of course i was able to scrub it off, but i was surprised how well it worked...on me. i will still order more. i like it better than liquid alternatives. But, i will be more careful with how i extract the packets from the plastic bag!

very good

The blue dye works well on our pond.

I wrote a bad review on packaging before but decided to try product again because I like the way the product works in the pond (Once you get it In The Pond!!). The blue dye still reappears on garage floor from leakage after opening outer bag months ago.This time I opened the new outer bag next to the pond but blue powder again shows up on pants, shoes, grass, etc. because of broken inner bag again.It shouldn’t be that difficult to package powder better.

Just drop the bag in and no mess! It is so easy to use unlike the bottles of blue dye which I always manage to get all over my hands. We have a 1 acre pond and the 2 pak is enough coverage. It lasts most of the summer here in Indiana.
